Detailed Description

The technical contents and features of the present disclosure will be described in detail below by referring to the preferred embodiments and the drawings, and the present disclosure provides a secondary weight adjusting device for a weight training apparatus that can be widely applied to various exercise apparatuses having a weight training box, and those skilled in the art can understand that the description terms of the present embodiment belong to the upper description without limiting the application field, for example, the material or shape terms include and are not limited to the material or shape specified by the description, and the position terms include and are not limited to the arrangement, the proximity, the connection, or the adjacency. The term "a" or "an" includes one and more than one of a plurality of elements. In the present specification, directional terms such as "upper", "lower", "inner", "outer", "top" and "bottom" are used only as exemplary terms with reference to a normal use direction, and are not intended to limit the scope of claims.

As shown in fig. 1 to 4, a preferred embodiment of the present disclosure is exemplified by a weight training apparatus having a weight training box, the weight training box has a main weight device 10, the main weight device 10 includes a plurality of main weight members 12 stacked on each other, a vertically extending guide rail 14 is disposed behind the main weight device 10, and the main weight members 12 can move up and down along with a cable 16.

The present disclosure provides a sub-weight adjusting device 20 comprising at least one sub-weight 22 and a selecting device 23, wherein the number of the sub-weight 22 is adjusted according to the product requirement and the load design of the weight training device, the number of the sub-weight 22 in the preferred embodiment is 6, and each sub-weight 22 is hollow as an example. The sub-weights 22 are provided inside the guide rail 14 such that the sub-weights 22 move up and down in the vertical direction adjacent to the main weight device 10, and the sub-weights 22 may be arranged in an array in the horizontal direction, or may be arranged linearly in the horizontal direction.

As shown in fig. 3 to 6, the selecting device 23 has a base 24, a selecting member 25, and at least one positioning member 30. The base 24 can be a housing or a combination of multiple components, the base 24 is disposed on the top of the main weight device 10, the selecting element 25 is pivotally disposed on the base 24, the selecting element 25 in the preferred embodiment is a knob as an example, the selecting element 25 has a disk 27, the disk 27 has at least one positioning portion 28, the positioning portions 28 in the preferred embodiment are recesses recessed in the surface of the disk 27 as an example, the positioning portions 28 are arranged on the surface of the disk 27, the recessed depth of each positioning portion 28 is different, and a guiding inclined surface 29 is disposed between each positioning portion 28. The depth of the recess of the positioning portion 28 in the preferred embodiment gradually increases or decreases in sequence according to the rotation direction of the selecting member 25, so as to make the operation of adjusting the auxiliary weight easier.

The positioning members 30 in the preferred embodiment are rod bodies, the number of the positioning members 30 is 2 as an example, each positioning member 30 is movably inserted through the base 24 along the horizontal direction, one end of each positioning member 30 abuts against the positioning portion 28 of the selecting member 25, and the other end of each positioning member 30 extends towards the auxiliary weight member 22. Each positioning element 30 is elastically restorable on the base 24, and a spring 32 is sleeved between the positioning element 30 and the base 24 in the preferred embodiment, so that two ends of the spring 32 respectively abut against a boss 33 of the positioning element 30 and the inside of the base 24, and the positioning element 30 is pushed toward the secondary weight element 22 by the elastic force of the spring.

With the above-mentioned components of the present disclosure, when the selector 25 rotates together with the disc 27, the positioning member 30 directly abutting against each positioning portion 28 may extend to different lengths toward the secondary weight member 22 in accordance with different recess depths of each positioning portion 28. As shown in fig. 7 to 10, when the positioning members 30 have different extending lengths, the positioning members 30 can penetrate through the centers of the auxiliary weight members 22 with different numbers, and when the main weight device 10 moves up and down, the positioning members 30 can synchronously drive the auxiliary weight members 22 to move up and down.

Because the auxiliary weight parts 22 are arranged behind the main weight device 10 in a linear or matrix shape along the horizontal direction, the whole weight adjusting device has a relatively simple volume, moreover, the extension length of the positioning part 30 of the selecting part 25 can be changed to drive different numbers of the auxiliary weight parts 22, the guide inclined plane 29 is arranged between the positioning parts 28 of the disc 27, when the selecting part 25 rotates, the positioning part 30 can easily abut against different positioning parts 28 along the guide inclined plane 29, so that the operation mode of the present disclosure is simpler and more convenient, the rotating torque force is relatively light, if the variability of the whole load is increased, more segment type load effects are achieved, and the training effect of increasing the micro load change can be achieved only by increasing the number and the depth change of the positioning parts 28 of the selecting part 25.
